Qt slot public or private

By Mark Zuckerberg

This compile-time check of signals and slots feels just so much better. And thus you also port any existing code to it. Including some which uses the pimpl approach for some public classes, borrowing Qt’s macros Q_PRIVATE_SLOT, Q_D & Co.:

Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's Private slots question | Qt Forum Slots conceptually are public interface, since their main purpose is inter-object communication. If you really need a function to be private that function shouldn't be a slot too, it should be just a private member function (if call that function internally Qt for Beginners - Qt Wiki public / protected / private slots; that mark the different methods that need to be extended. SIGNAL and SLOT are also two very important and useful macros. When a signal is emitted, the meta-object system is used to compare the signature of the signal, to check Qt Slot Public or Private | Avangarde Home

Signals and Slots in Depth. The signals and slots mechanism is fundamental to Qt programming. It enables the application programmer to bind objects together without the objects knowing anything about each other. We have already connected some signals and slots together, declared our own signals and slots, implemented our own slots, and emitted ...
